Find the electric potential 3.00 cm from a proton?
The electric potential from a point charge can be calculated using the equation V = kq/r, where k is the electrostatic constant (8.99 x 10^9 Nm^2/C^2), q is the charge of the proton (1.6 x 10^-19 C), and r is the distance from the charge (0.03 m). Substituting these values into the equation gives V = (8.99 x 10^9)(1.6 x 10^-19) / 0.03 ≈ 4.78 x 10^6 V.
What are the factors affecting the strength of a magnetic field?
Electronegativity- the relative ability of an atom's nuclues to attract a pair of bonding electrons in the valence energy level. 1) size of atom- electronegativity decreases with the increase in size of the atom because there are more electrons between the nucleus and the valence level: 'electron shielding' 2) # of valence electrons- the more valence electrons, the higher the electro negativity Metals lose electrons when forming cations, therefore the more reactive metals have lower electronegativity. Non-metals gain electrons when forming anions, therefore more reactive non-metals will have higher electronegativity.
Example of law of mass action?
Chemical Equilibria Heat is energy flowing from a high temperature object to a low temperature object. When the two objects are at the same temperature, there is no net flow of energy or heat. That is why a covered cup of coffee will not be colder than or warmer than the room temperature after it has been in there for a few hours. This phenomenon is known as equilibrium. In this example, we deal with the flow of energy.Equilibria happen in phase transitions. For example, if the temperature in a system containing a mixture of ice and water is uniformly 273.15 K, the net amount of ice formed and the melt will be zero. The amount of liquid water will also remain constant, if no vapour escape from the system. In this case, three phases, ice (solid) water (liquid), and vapour (gas) are in equilibrium with one another. Similarly, equilibrium can also be established between the vapour phase and the liquid at a particular temperature. Equilibrium conditions also exist between solid phase and vapour phases. These are phase equilibria.Chemical reactions may not be as complete as we have assumed in Stoichiometry calculations. For example, the following reaction are far short of completion. 2 NO2 = N2O43 H2 + N2 = 2 NH3H2O + CO = H2 + CO2Let us consider only the first reaction in this case. At room temperature, it is impossible to have pure NO2 or N2O4. However, in a sealed tube ( closed system), the ratio [N2O4] ------- [NO2]2is a constant. This phenomenon is known as chemical equilibrium. Such a law of nature is called the law of mass action or mass action law.Of course, when conditions, such as pressure and temperature, change, a period of time is required for the system to establish an equilibrium.Before we introduce the mass action law, it is important for us to identify a system or a closed system in our discussion. The law provides an expression for a constant for all reversible reactions.For systems that are not at equilibrium yet, the ratio calculated from the mass action law is called a reaction quotient Q. The Q values of a closed system have a tendency to reach a limiting value called equilibrium constant Kover time. A system has a tendency to reach an equilibrium state.A Closed System for the Equilibrium StateIn order to discuss equilibrium, we must define a system, which may be a cup of water, a balloon, a laboratory, a planet or a universe. Thus, for discussion purpose, we define an isolated portion of the universe as a system, and anything outside of the system is called environment. When the system under consideration is isolated from its environment in such a way that there is no energy or mass transferred into or out of the system, the system is said to be a closed system.In a closed system, changes continue, but eventually there is no NET change over time. Such a state is called an equilibrium state.For example, a glass containing water is an open system. Evaporation let water molecules to escape into the air by absorbing energy from the environment until the glass is empty. When covered and insulated it is a closed system. Water vapour in the space above water eventually reaches a equilibrium vapour pressure.In fact, measuring of temperature itself requires the thermometer to be at the same state as the system it measures. We read the temperature of the thermometer when heat transfer between the thermometer and the system stops (at equilibrium).Equilibrium states are reached for physical as well as chemical reactions. Equilibrium is dynamic in the sense that changes continue, but the net change is zero.Reversible Chemical ReactionsHeat transfer, vapourization, melting, and other phase changes are physical changes. These changes are reversible and you have already experienced them. Many chemical reactions are also reversible. For exampleN2O4=2 NO2colourlessbrownand N2 + 3 H2 = 2 NH3are reversible chemical reactions.The Law of Mass ActionThe law of mass action is universal, applicable under any circumstance. However, for reactions that are complete, the result may not be very useful. We introduce the mass action law by using a general chemical reaction equation in which reactants A and B react to give product C and D. a A + b B --> c C + d D where a, b, c, d are the coefficients for a balanced chemical equation.The mass action law states that if the system is at equilibrium at a given temperature, then the following ratio is a constant.[C]c [D]d------------- = Keq[A]a [B]bThe square brackets "[ ]" around the chemical species represent their concentrations. This is the ideal law of chemical equilibrium or law of mass action.The units for K depend upon the units used for concentrations. If M is used for all concentrations, K has unitsMc+d-(a+b)The Reaction Quotients Q and the Equilibrium Constants KIf the system is NOT at equilibrium, the ratio is different from the equilibrium constant. In such cases, the ratio is called a reaction quotient which is designated as Q. [C]c [D]d------------- = Q[A]a [B]bA system not at equilibrium tend to become equilibrium, and the changes will cause changes in Q that its value approaches the equilibrium constant, KQ ® Keq.

What is the relationship between the electric potential and electric field according to the equations V kq/r and E kq/r2?
The relationship between electric potential (V) and electric field (E) is that the electric field is the negative gradient of the electric potential. This means that the electric field is the rate of change of the electric potential with respect to distance. The equations V kq/r and E kq/r2 show that the electric field is inversely proportional to the square of the distance from the charge, while the electric potential is inversely proportional to the distance from the charge.

Determine the amount by which the electric force between two charges is increased when the distance between the charge is halved?
E=kq/r^2 So, when the distance id doubled, the change is taken down by a factor of 1/4. In other words, if the distance was 3, and then 6, this is what would happen: E=kq/(3)^2=kq/9 and then when r = 6, E=kq(6)^2=kq/36=kq/9*1/4 Thus, reduced by a factor of four or multiplied by 1/4
What is the relationship between the gravitational force and the distance between two objects as described by the formula kq/r2?
The relationship between the gravitational force and the distance between two objects is described by the formula kq/r2. This formula shows that the gravitational force between two objects is inversely proportional to the square of the distance between them.
